conception dates?

During my 1st visit at 6 weeks my doctor put my due date at november 11th by ultrasound measurements since I wasn't sure of my last period, I just knew it was the beginning of february. Is there any way I could have concieved on march 4th? I hear early ultrasounds are very accurate and I don't believe it would be off on conception by 2 whole weeks. I'm jw because I had a drunk incident on march 4th and not sure if I had intercourse. Please don't judge.

There was a girl on here asking because her incident was 3 weeks apart and she was still worried.....

It's tricky because sperm can live inside you up to 5 days... but on the flip side, when you ovulate, the egg is only good for up to 24 hours I read and hear. And you ovulate between 12 to 14 days after your period starts.

If this helps. My due date is 11/10. I was inseminated on feb 18. My last period was feb 7. So I know the actual conception date. Hopefully this info will calculate yours. I normally ovulate sooner than others but it gives u a better idea. No drugs involved in the stimulation for ovulation FYI

I think a 6 week ultrasound is pretty accurate, as they get less accurate as the weeks go on. The reason they do the early ultrasound now is specifically for dating purposes so it should be pretty close. However; while it's more likely you ovulated in mid-February everyones cycle is different!

I guess I should also add he calculated my lmp to be feb 5th. And conception around the 19th. I don't see any possible way march 4th would be the date. And with the comment about sperm living for a few extra days that would only push conception up to march 5th or 6th which is a lot later than what my doctor said.

Yeah and I mean say conception was march 4th and I was pushed back 2 weeks....... They usually don't even pick up baby's at 4 weeks pregnant! I would have only been 4 wks pregnant at the ultrasouns if it was the march 4th incident.

This has always confused me because if you ovulate only 1 day then how can you be fertile for days before you ovulate?? How can you know your exact date if conception? My lmp was Feb. 7th, I supposedly ovulated on Feb. 22nd, my 1st due date was Nov. 13th but my 2nd ultrasound says Nov. 9th.. I have no clue of any of this.. I just know I got pregnant in Feb..

I do not ovulate at the typical time most women ovulate as I have a shorter menstrual cycle. My luteal phase (days following ovulation leading up to period) is extra long. I know the exact date and time we conceived bc I was sick leading up to, and my husband was out of town following. My OB told me my due date was much later than I calculated from my last cycle. The scan even said I was due later (baby measured 6 weeks 2 days when I was actually 7 weeks) along. Implantation length also plays a role in when you receive a positive pregnancy as well as the gestational age of the fetus. I have also measured behind on every following scan...I must have a skinny baby :)

Initially my doctor went off my lmp so I was put at a due date of I think Nov 12th, however I have a 32 day cycle, so by my calculations I conceived on Feb 26thish. Had the dating ultrasound and sure enough I conceived on or around that date. Due Nov 18th and that's the day they are sticking with. I'd go with ultrasound.

So with the 2 week gap should I be worried or not? Every ultrasound has also gone with the ultrasound estimated conception date of feb 19th.. And I understand that that doesnt exactley mean sex happened that day. But even if sex happened a few days before or after that, should I be concerned with the march 4th incident?

My lmp was feb 7th and I am due nov 13/14th.. And I had a positive preg test by march 7th... So if your dating ultrasound agrees with a edd of around the 11th, I wouldn't think there was any possibility of sex on the 4th being conception...

My lmp was 2-2-12, I was told my due date according to my lmp is 11-5-12, but by ultrasound my due date is 11-5-12. The date I'd conception is supposedly 2-16-12. I always wondered if any of these dates added up, but I never got an exact answer. I know it's hard because every females body is different.

Haha thank you. I think about it every once in a while and it bothers me some. But I'm pretty positive there's no way that that was the incident that got me pregnant. My bf and I were having a lot of unprotected sex through out February soooo I'm sure it was sometime mid February.

@DivaMommy... You're fertile for days before you ovulate not bc your ovulation day is uncertain but bc of how long sperm can live. Let's say you ovulate on day 14 of your cycle. Your egg is viable for 24 hours, so it can be fertilized anytime on days 14 & 15. Sperm, however, is viable much longer. It can live 4-5 days inside you. Let's say you have sex on day 9. That's 5 days before you ovulate, but you could still get pg bc sperm might still be hanging around waiting for your egg when it's released. But imagine what happens if you have sex on day 16. That's 2 days after you ovulate (and outside the 24-hour window of egg viability), so you wouldn't get pg no matter how long the sperm live inside you. You have to have both sperm and egg present at the right time. We ladies can keep the guys waiting, but we won't wait around for them. Hth. =)
